Unable to upload files to datastore - vCenter Server 6.5

Error -   “The operation failed for an undetermined reason. Typically this problem occurs due to certificates that the browser does not trust. If you are using self-signed or custom certificates, open the URL in a new browser tab and accept the certificate, then retry the operation.”

Solution:

Open vCenter Server address in a browser. https://vCenterServerName.DomainName.com, not the complete vSphere web client address.

Click on Download trusted root CA Certificates.

Unzip the download.zip file

Open the folder according to your Operating System

In my case, some of them are already installed, and others are not.

If you have many files in the operating system folder, then sort it according to the file type  

Double click on the .crt files and click on Install Certificate

On the ‘Certificate Import Wizard’ , Select Local Machine and click Next

On the Next Screen, Select ‘ Place all Certificate in following Store’ option, and Select Trusted Root Certification Authorities by clicking the browse button.

Click Finish and do the same for the rest of the certificate.

Restart the browser, and you should be able to upload the files.

How to troubleshoot SCCM Task Sequence Deployment Errors

The first thing is to make sure that Command Support is enabled in Boot Image. 

Press f8 when you get an error on Task Sequence.

The second thing is that you have to access the smsts.log file from x:\windows\temp\smstslog\smsts.log

Copy the file to a network location

Example:  net use s: \\fileserver\share /user:domain\username password

Copy smsts.log to s:

Delete network Drive – net use s: /delete

Open the file using cmtrace.exe

Guest VM not getting an IP address from DHCP Server

Situation:

I was setting up a Windows 10 client VM so that I can capture the image using MDT Server.

I have noticed that Windows 10 is not receiving an IP address from the DHCP server even though both the machine resides in the same port group.

I also have a client VLAN - VLAN-150. All my client machines are connected to that VLAN

Solution:

My ESX host switch doesn’t have the client VLAN configured. First, checked and made sure that the ESX hosts Ethernet ports are tagged in the client VLAN on the Physical Switch.

Created a new port group called Client on the ESXi switch with VLAN 150. Make sure you do this on all the ESXi hosts.

Edit the Guest VM settings and changed the Network to Client
